The dam, designed by USDA NRCS, is an earth-type structure with a height of 23.7 feet and a length of 545 feet. It has a storage capacity of 69 acre-feet and serves a drainage area of 155 acres, with a maximum discharge of 114 cubic feet per second. The dam is situated on Long Branch and is under the jurisdiction of the local government, with no state regulatory oversight.
Despite being classified as having a low hazard potential, the dam has a moderate risk assessment rating. It lacks a formal condition assessment and emergency action plan, indicating potential vulnerabilities that may need to be addressed in the future. The dam's spillway is uncontrolled with a width of 20 feet, and it does not have outlet gates for water release. Overall, Troublesome Creek Watershed Dam S-75 plays a critical role in mitigating flood risks in the area, but ongoing monitoring and maintenance efforts may be necessary to ensure its continued effectiveness and safety for the surrounding community.
